• ASARCO » Refining

    Compared to other metals, copper is very ductile, meaning that it can be drawn through a tiny hole into very fine wire without breaking. Refining improves the ductility of copper so that extremely fine wires can be drawn. Impurities increase the chance that the wire will break during the drawing process.Copper conducts electricity

    Secondary production. Copper and alloys with a high copper content are recycled to obtain pure copper. The metals are heated with oxygen-enriched air, which oxidizes most of the metals, but not the copper or any precious metals, forming a slag that can be removed. The Isasmelt process described above is often used for secondary copper production.
